The smallest unit of life that can carry our all functions
cell
Cranium, femur, humerus, tibia, fibula
the skeletal system
This muscle supports your circulatory system by pumping blood throughout the body
heart
How does the nervous system work with all the other systems of the body?
it controls them
Smooth muscle is best described as what working together? (hint: tissues, organs, cells, organ systems)
cells
The levels of organization for multicellular organisms
cell--> tissue--> organ--> organ system--> organism
esophagus, stomach, small intestine, large intestine
the digestive system
This organ controls all other organs and systems
brain
How does the respiratory system work with the circulatory system
The respiratory and circulatory systems work together to oxygenate the body and remove carbon dioxide.
The respiratory system brings in oxygen, and then the heart pumps this oxygenated blood to tissues, where it is exchanged for carbon dioxide, which returns to the lungs for exhalation.
We breathe in _________ and breathe out ________.
Oxygen, carbon dioxide
the muscles we can control
voluntary muscles
brain, nerves, spinal cord, neurons
the nervous system
These two body systems aid your body in movement
skeletal and muscular
How does the digestive system work with the muscular system?
The muscular and digestive systems collaborate through involuntary smooth muscle contractions to move food, mix it with enzymes, and eliminate waste.
Why does your heartbeat increase when you exercise?
The heartbeat increases to supply more blood to all of the muscles involved in the exercise.
the muscles we cannot control
involuntary muscles
lungs, trachea, alveoli, nose
the respiratory system
A long tube that carries chewed food to the stomach.
esophagus
How would your nervous system aid your muscular system if you were to touch a hot stove?
The nerves in the hand send a signal to the brain, and the brain sends a signal to the muscles to move the hand off of the stove.
This body part absorbs the nutrients from the food that is digested in the stomach and passes them along to the blood
small intestines
The _______ transport blood to the heart, and ________ transport it away from the heart.
veins, arteries
heart, veins, arteries, capillaries
the circulatory system
The part of your body that carries messages to the brain
spinal cord
How does the digestive system work with the circulatory system?
The nutrients gained from the digestion of food by the digestive system are transported throughout the body by the circulatory system.
How do your respiratory and circulatory system transport blood through your body?
By exchanging gases in the lungs and pumping oxygenated blood throughout the body in a continuous loop.
The heart pumps deoxygenated blood to the lungs to receive oxygen, which is then returned to the heart and pumped through arteries to tissues, returning via veins.
